Application filed July 1, 1912- Serial No. 706,870.

To all whom-it may concern:

Be it known that I, S M EL B. Banner, a resident of Devon, in the county of Chester and State of Pennsylvania, have invented certain newand useful Improvements in Devices for Welding Barrels, whereof the following is a specification, reference being I t-ion, to ether with rotating parts which are adapted ,to travel about the barrel and are pressed against the flange ,of'the barrel to bring about welding operation.

A further object ot the invention is to provide a device of the aboye character,

wherein a stationary chuck ring may be caused to ,en a e e outer face of the flange oi the barre ivh i l e a plurality of welding rollers are pressed aga nst and rotated bodily while in contact with, the flange ot: the head for bringing about a welding of the head to the body of the barrel.

These and other objects will in part be obvious, and will in part be hereinafter more fullydisclosed.

In the drawings, Figure I, is a plan view of a welding device embodying my improvements. Fig. II, is a part vertical sect on and part side elevation of the same. I*1g. HT, is a view similar to FignII, showing a modification of the invention,

The invention consists generally in providing a stationary support on which the head of the barrel may rest, during .the welding operation, and a stationary chuck which, as shown in Fi s. I, and I I, engage the outer face of the ange of the body of the barrel, while, as shown in Fig. II, said stationary chuck engages the inner face oi the flange on the head of the barrel. Cooperating with this stationary chuck are welding rollers which are carried by .a rotat ng head. T hcse rollers are mounted on swinging arms which are caused to rcss the rollers against the parts to be welt ed.

Referring more in detail to the drawings,

my improved welding device consists .o a

supporting base 1, from which rises a s t -z 1i i l-' ard 2. This standardis mounted in a socket 3, termed in the base 1. The standard is held from rotation by any suitable means. Mounted on the upper end of the standard is a stationary support 1, on which the head of the barrel is adapted to rest with the barrel in vertical position. Rising also from the supporting base 1, are a plurality of standards 5, which carry a stationary chuck 6, at their upper ends. This stationary chuck 6, is in the form of a ring, and is so'shaped as to receive the flange 7, of the bodyjof the barrel '8. The upper inner corner of the chuck is chamtered, so as to permit the barrel to be readily inserted in the stationary chuck. The inner surface of the stationary chuck is of such width as to engage the flange of the head of the barrel from a point a jacent the lnner surface of the head to the outer edge of the flange. Y

A plurality of welding rollers 9, cooperate with the stationary chuck in weld' the flap e of the head to the flange of .tliii body of t to barrel. As herein shown, I have provided four welding rollers, each of which is carried b a pivoted arm 10. The arm 10, is pivote at 11, to a rotating head 12. The rotating head 12, encircles the stationary standard 2, and is provided with suitable bearings 13, and 1ft, which engage the standard and the upper surface or the socket 3.

This rotating head carries a sliding collar 15, Which is splined thereto so as to slide lOl itudinally on the head. The collar 15, is ormed with outwardly projecting arms 16, and links 17 are pivoted to these arms at 18. The other ends'of the links l'i, are pivoted at 19, to the arms 10, which carry the Welding rollers The collar 15, is slid 0n the rotating head by a rock lever 20, the horizontal 'arm of which pivotally attached to a sliding collar 21, whose upper face abuts against the collar 15. As readily seen in Fig. 11, the collar '21, will 'impar t vertical moveipent to the collar 15, without rotatin' with'lhe latter. Tl re other arm ot the rec I level 20, is connected to a plunger 22, of a negmgtically controlled cylinder 23'. The liea 1 carries a bevel ear 24, at its lower end, which meshes wit a bevel gear 2:"), on ,t e main shaft 26, which is driven by a pn ley 27, p

In Fig. III, I have shown a slightly modicd form of the invention in that the stationary support and stationary chuck are formed as one'in a disk 28, which is secured by a screw 29, to the upper end of the standard 2. The rotating head 12, is operated through the bevel gears 24, and 25, as above noted. This stationary chuck engages the inner face of the flange of the head, While thewelding rollers 30, engage the outer face of the flange of the body of the barrel. These rollers are carried by arms pivoted at 31, to the rotating head 12, of the barrel, and the arms are swung about their pivots by links 32, which are pivoted to a sliding collar 33. The sliding collar 33, is moved endwise on the rotating head by a rock lever 20, which is connected to a plunger 22,

controlled by the pneumatic cylinderv 23.

In the operation of my device, the collar is slid on the rotating head, so as to move the welding rollers away from the stationary chuck. The barrel head is inserted in the end of the barrel, and the partsto be welded are heated to the proper welding temperature. the stationary support with the flange of the barrel or the flange of the head in engagement with the stationary chuck. The pneumatic cylinder is then operated to bring the Welding rollers into contact with the parts to be welded, and the main shaft causes the rotating head to revolve and the rollers to pass over the flange of the head or the flange of the barrel, and coiiperating with the stationary chuck, forces the two flanges into welding contact. As soon as the parts are welded, the rollers are moved out of contact with the barrel and the same may be readily withdrawn from the device.

From the above description, it will be apparent that I have provided a welding device which is entirely free of any heating apparatus, and that the barrels to be welded may be quickly manipulated so that the preheating of the barrel is suflicient for the Welding operation. Byarranging the standard in a vertical position, the barrel will be properly supported during the welding operation.

It is obvious that minor changes in the details of construction and the arrangement of the parts may be made, without departing from the spirit of the invention, as set forth in the appended claims.

Having thus described my invention, I claim:

1. A device for welding metal barrels or the like, including in combination a chuck for engaging one side of the parts to be welded, a head, means for giving said head and chuck relative movements of rotation, a welding roller carried by said head, and means for moving said welding roller into engagement with the opposite side of the The barrel is then placed on same, a rotating head, a welding roller or rollers carried by said head and adapted to engage the parts to be welded, and a stationary chuck engaging the opposite side of the parts to be welded and with which said welding roller, or rollers cooperate.

3. A device for welding metal barrels or the like including in combination, a vertical standard, means carried thereby for engaging the end of the barrel and for supporting the same, a rotating head, a welding roller or rollers carried by the head, means for moving said welding roller or rollers into contact with the flange of the head, and a stationary chuck for engaging the flange of the barrel and with which said roller, or rollers coiiperate.

4. A devicefor welding metal barrels or the like including in combination, a vertical stationary standard, means carried thereby for engaging the end of the barrel for supporting the same, a rotating head mounted on said standard, arms pivoted to said rotating head, rollers carried by said arms, a sliding collar, devices for connecting the sliding collar with said arms for moving the rollers into and out of contact with the parts to be welded, and a stationary chuck cooperating with said Welding rollers.

5. A device for welding metal barrels or the like including in combinationfa supporting device, a-vertical standard carried thereby, a rotating head mounted on said standard, means for rotating said head, arms pivoted to said rotating head, rollers carried by said arms, a sliding collar mounted on said head, links connecting said sliding collar to said arm and so disposed as to move the rollers into and out of contact with the parts to be welded, standards rising from said base, and a stationary chuck carried by said last named standards, engaging the outer face of the flange of the body of the barrel and coiiperating with said welding rollers.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this twenty-fifth day of June, 1912.
